2. The method as claimed in claim 1 , wherein the wireless transceivers are WiFi transceivers.
3. The method as claimed in claim 2 , wherein the predefined wireless network identifier is a Service Set Identifier.
4. The method as claimed in claim 1 , wherein the wireless transceivers are Bluetooth transceivers.
5. The method as claimed in claim 4 , wherein a defined Personal Identification Number code is exchanged for authentication purpose.
6. The method as claimed in claim 1 , wherein the signaling protocol is the Session Initiation Protocol.
7. The method as claimed in claim 1 , wherein the wireless phone is a videophone.
8. The method as claimed in claim 1 , wherein the step of initiating includes one of: a long press on a specific key, a specific key press sequence, a specific simultaneous press on a combination of keys, a press on a dedicated key or switch, or an item in a menu that can be selected by navigating to this item.
9. A communication system comprising a first wireless phone (A) and a second wireless phone (B) able to exchange data using a signaling protocol in an audio/video intercom mode, each of said first and second wireless phones each comprising: means for initiating a direct communication between said first wireless phone and said second wireless phone via a first stimulus on the first wireless phone and a second stimulus on the second wireless phone, wherein the first stimulus is not identical to the second stimulus; a memory (MEM_A, MEM_B) containing a first predefined IP address (IP_A) and a first signaling protocol identifier (SIP_A) corresponding to the first wireless phone, a second predefined IP address (IP_B) and a second signaling protocol identifier (SIP_B) corresponding to said second wireless phone, and a predefined wireless network identifier (SSID), wherein the first and second predefined IP addresses and signaling protocol identifiers are fixed and known, and wherein the predefined wireless network identifier comprises a single fixed and known SSID identifier attributed to both the first and second wireless phones; and a transceiver for establishing a direct communication between the first wireless phone and the second wireless phone using the signaling protocol on the basis of the first and second predefined IP addresses, the first and second predefined signaling protocol identifiers and the predefined wireless network identifier, wherein after a start of the audio/video intercom mode, both the first wireless phone and the second wireless phone are forced to use the predefined wireless network identifier (SSID), to establish video and voice calls between the two wireless phones using the signaling protocol without a network, wireless base station, or signaling protocol server.
10. A wireless phone (A) comprising: means for initiating a direct communication between said wireless phone and another wireless phone via a first stimulus on the wireless phone and a second stimulus on the another wireless phone, wherein the first stimulus is not identical to the second stimulus, wherein the wireless phone and the another phone are able to exchange data using a signaling protocol in an audio/video intercom mode; a memory (MEM_A) containing a first predefined IP address (IP_A) and a first signaling protocol identifier (SIP_A) corresponding to said wireless phone, a second predefined IP address (IP_B) and a second signaling protocol identifier (SIP_B) corresponding to said another wireless phone, and a predefined wireless network identifier (SSID), wherein the first and second predefined IP addresses and signaling protocol identifiers are fixed and known, and wherein the predefined wireless network identifier comprises a single fixed and known SSID identifier attributed to both the wireless phone and the another wireless phone; and a transceiver for establishing a direct communication with the another wireless phone using the signaling protocol on the basis of the first and second predefined IP addresses, the first and second predefined signaling protocol identifiers and the predefined wireless network identifier, wherein after a start of the audio/video intercom mode, both the first wireless phone and the second wireless phone are forced to use the predefined wireless network identifier (SSID), to establish video and voice calls between the wireless phone and the another wireless phone using the signaling protocol without a network, wireless base station, or signaling protocol server.
